Network can be used two kinds of group calling modes: a kind of Shi Dan community group calling mode, and eat dishes without rice or wine to adopt broadcast mode to transmit descending group calling data; Another kind is the multi-plot joint transmission means, eats dishes without rice or wine to adopt MBMS(Multimedia Broadcast Multicast Services, the multimedia multicast broadcasting service) mode transmits descending group calling data.

Based on above group-network construction, the network attachment schematic flow sheet of the terminal that Fig. 2 provides for the embodiment of the present invention (being mobile terminal here), in this flow process, terminal is by NAS message, as Attach(adheres to) request message and PDN Connectivity Request(PDN connection request) message, report the group service ability information of oneself to network side, this flow process can comprise:

Step 201, terminal (hereinafter to be referred as UE) sends Attach Request(to eNB and adheres to request), wherein carry cluster network and select indication information.In addition, whether the embodiment of the present invention supports this UE the indication information of multi-plot joint transmission means (being the TMBMS mode) by Attach Request, and the maximum downstream rate of the group service supported of this UE sends to network side.

During concrete enforcement, Attach Request message and PDN Connectivity Request belong to NAS(Non-Access Stratum, Non-Access Stratum) message, usually send together.In the embodiment of the present invention, by Attach Request message, carry the indication information of whether supporting TMBMS, carry the maximum downstream rate of the group service that UE supports by PDN Connectivity Request message.

Concrete, UE can be used the reservation bit in existing Attach Request message, carries the indication information of whether supporting TMBMS.For example, carry " TMBMS Supported " indication information in UE " UE network capability(UE network capabilities) " information unit in Attach Request message, this indication information can take 1bit, be used to indicate whether support TMBMS(such as, 0 sign is supported TMBMS, and 1 means not support TMBMS).Table 1 shows the form of " UE network capability " information unit, and wherein, the bit6(in octet7 i.e. the 6th bit of the 7th byte) whether support TMBMS for meaning UE.

Following steps 202 ~ 217 are basic and the general networks attachment flow is similar, are summarized as follows:

Step 202, eNB selects the global unique temporary identity (GUTI) of carrying in indication information and Attach Request according to cluster network, perhaps, according to other TMSE selection strategy, determine the TMSE that will adhere to, and this Attach Request is sent to this TMSE.

Step 203, if be shown TMSE-new in the TMSE(figure that in step 202, eNB determines) be shown TMSE-old from the TMSE(figure adhered to before UE) different, TMSE-new also will obtain subscriber identity information and authentication relevant information from TMSE-old.If the TMSE adhered to before the TMSE that in step 202, eNB determines and this UE is identical, or this flow process is the initial network attachment flow after the UE start, and step 203 can not occur.

Step 204, carry out bi-directional authentification between TMSE and UE, this process is standard 3GPP protocol procedures.But this step is selection operation.

Step 205 ~ 208, after the authentication success, TMSE initiates the user position update process, in this process, TMSE sends Update Location(position to HSS and upgrades) message, HSS sends Insert subscriber data(according to this message to TMSE and inserts subscription data) message, thus insert the user data of this UE in TMSE.But this process is selection operation, if occurrence positions does not upgrade, can not carry out this process.

Step 209, TMSE is that UE creates default bearing, and is UE distributing IP address and cluster group IP address, sends initial context and sets up request (adhere to and accept message (Attach Accept)) to eNB.

Step 210, eNB sends RRC and connects reconfiguration message to UE, wherein comprises EPS(Evolved Packet System, evolved packet system) RB ID and Attach Accept message.

Step 211, UE sends the RRC connection and has reshuffled message to eNB.

Step 212, eNB sends initial context and sets up response (Initial Context Response) message to TMSE.The TEID that comprises eNB in this Initial Context Response message and the ，Gai address, address of eNB are for the downlink business of cluster S1 interface user plane (S1_Tu) reference point.

Step 213, UE sends (Direct Transfer) message that direct transfers to eNB, and this message comprises has adhered to (Attach Complete) message.

Step 214, eNB is used up NAS message transfer to forward Attach Complete message to TMSE.

Step 215, all forming that TMSE is this UE place built cluster group downlink bearing link.For each group, TMSE sets up TMSE to the unidirectional GTP-U tunnel between eNB, the downlink data for carrying from TMSE to eNB.

Step 216 ~ 217, TMSE is sent in the net Indication message to scheduling Server.

By above-mentioned network attachment process, group service request UE gives the i.e. service TMSE of this UE of the accompanying TMSE(of this UE by its clustering capability information reporting), the service TMSE of this UE sets up default bearer for this UE, and carries out the group service registration.

When UE need to carry out group service, trigger group call establishment process, in this process, the group service ability information that network side reports in the network attachment process according to this called UE, for this called UE is selected suitable group calling transmission means and is selected suitable descending group calling bearer rate.As shown in Figure 3, after calling UE (UE1) and eNB set up RRC and be connected, this flow process can comprise:

Step 1, UE1 initiates group calling and sets up request, this request passes through through eNB1 the service TMSE that TMSE1(TMSE1 is UE1).

Step 2 ~ 3, TMSE1 is converted to session initiation protocol (Session Initiation Protocol, SIP) by this group calling request of setting up and invites (Invite) message, and sends to scheduling Server.If there is extremely notifying this group calling of TMSE to discharge.

Step 4, after scheduling Server authorizes successfully to UE1,181 Temporary Responses that SIP Invite message is corresponding send to TMSE1, and notice TMSE1 should call out well afoot.

Step 5 ~ 10, if UE1 in Idle state, TMSE1 sets up up link for the calling subscriber, sends initial context and sets up request to eNB1, to trigger UE1, carries out RRC and connects and reshuffle.If calling UE 1 is in connected state, TMSE1, for after the calling subscriber sets up default bearing, initiates dedicated bearing and sets up request, to trigger UE1, carries out RRC and connects reprovision.

Step 11, after scheduling Server receives SIP Invite message, the inquiry local data base, obtain the called UE (UE2 in Fig. 3 of group calling ... UEn) TMSE2 in all TMSE(Fig. 3 under ... TMSEn) address, and send respectively the service TMSE of Invite message to each called UE.

Step 12, the service TMSE(of called UE is TMSE2 for example), for called group of user, sending the group calling context and set up request message to eNB2, the request eNB of take is set up and is found context as cluster user.

In this step, TMSE2 is according to being attached to the group service ability information that the terminal that belongs to this group calling on this TMSE reports in the network attachment process, determine the maximum downstream rate adopted when setting up the group-calling service carrying, so that according to the descending group calling carrying of setting up between the downstream rate of determining and eNB2 on the S1 interface.When determining the maximum downstream rate of group-calling service carrying, the maximum downstream bit rate that can support according to all terminals that belong to this group calling that are attached to this TMSE2, adopt certain strategy, select suitable bearer rate, such as the minimum value in the maximum downstream bit rate that can select all terminals to support, as the downstream rate of the descending group calling carrying on the S1 interface.In the situation that the downlink bearing of the group calling about this group calling between TMSE2 and eNB2 is set up, above-mentioned group calling downlink bearing process of establishing can be omitted.

The group service ability information that TMSE2 also reports in the network attachment process according to UE2, determine the group calling transmission means (as adopted single community group calling mode or multi-plot joint transmission means, carrying out group calling) that UE2 is adopted, and the multicast transmission mode of determining is set up to request message by the group calling context and indicate to eNB2, so that eNB2, when carrying out the group calling downlink data transmission, adopts corresponding group calling mode to UE2 transmission trunking business downlink data according to this indication information.Concrete, if the indication information of the group calling mode that UE2 supports is for supporting the indication information of joint transmission mode group-calling service, TMSE2 supports joint transmission mode group-calling service to eNB2 indication UE2, so that eNB2 adopts the joint transmission mode, is that UE2 carries out the group calling downlink data transmission; If the indication information of the group calling mode that UE2 supports is not for supporting the indication information of joint transmission mode group-calling service, TMSE2 does not support joint transmission mode group-calling service to eNB2 indication UE2, so that eNB2 adopts the group calling of single community or individual calling mode, is that UE2 carries out the group calling downlink data transmission.

Step 13, it is that cluster user is set up vertical context that eNB sets up request message according to this group calling context, returns to the group calling context to TMSE2 and sets up response message.

Step 14 after this ~ 21 are basic and old process is similar, mainly comprise: after scheduling Server receives the off-hook 200OK message of the called UE that the service TMSE of any one called UE forwards, send group calling by 200OK message and set up response message to TMSE1, this message is carried the right of speech mandate simultaneously; TMSE1 sends group calling to UE1 and sets up response, wherein carries the right of speech authorization messages, is used to UE1 to authorize right of speech; ENB1 carries out NAS message and direct transfers, and after UE1 receives the right of speech authorization messages, sends the right of speech mandate to TMSE1 and completes message; Scheduling Server notify (INFO) message by SIP, carries right of speech and take content to TMSE2; TMSE2 sends right of speech and takies message to eNB2, in order to indicate eNB2 to send right of speech by broadcast mode, takies message to called UE.

After this, can carry out the group service transfer of data by the group calling carrying of setting up between calling UE and called UE.In this process, the group calling transmission means that eNB can support according to each terminal, for each terminal is selected suitable group calling transmission means, to terminal signalling of bouquet business downlink data.

Above flow process is sent as example and describes together with PDN Connectivity Request with Attach Request message, in existing standard, also allow PDN Connectivity Request message independently to send, in such cases, also can adopt and the similar mode of above-mentioned flow process, by Attach Request message and PDN Connectivity Request message, the group service ability information of terminal is reported to network side.

Further, the indication information of the group calling mode of supporting due to terminal, can between TMSE, move with the contextual information of terminal, but the group service maximum downstream rate that terminal is supported can not followed the context migration of terminal, therefore in the embodiment of the present invention, when the terminal occurrence positions upgrades, also in position updating process, report the own group service maximum downstream rate of supporting.Concrete, terminal can be carried on location update request message by the own group service maximum downstream rate of supporting and report current service TMSE, so that this TMSE is according to the group service ability of this terminal, select suitable group calling transmission means, and during the carrying of the descending group calling on setting up the S1 interface, select suitable bearer rate to carry out signalling of bouquet business downlink data.

Above flow process is that to take the network attachment of mobile terminal and group service implementation procedure be that example is described, and for the terminal of fixed station type, its network attachment and group service implementation procedure similarly, do not repeat them here.

By above description, can find out, the embodiment of the present invention is by the group service ability information of terminal to report oneself, make network side set up the group service carrying and to adopt suitable group service transmission means for this terminal according to terminal capability, thereby guaranteed the reception of terminal to the group service downlink data.
